The API AMMONIA TEST KIT is a mercury-free, salicylate test for fresh and saltwater fish, and measures ammonia levels from 0 to 8 ppm.

• Suitable for Freshwater & Saltwater aquariums

API® AQUARIUM SALT is made from evaporated sea salt and is a must-have for your aquarium! AQUARIUM SALT promotes fish health by improving gill function, making it easier for fish to breathe. It also provides essential electrolytes that fish need to reach peak coloration and vitality. These electrolytes may be lost each time you perform a partial water change, and will need to be replenished.

Use API AQUARIUM SALT in freshwater aquarium tanks when starting a new aquarium, and any time you perform a water change. Care should be taken when using salt in aquariums with live plants, as some plants may be sensitive.

Available Sizes: 16 oz, 33 oz, 65 oz

The API® COPPER TEST KIT allows you to easily and accurately monitor copper levels to maintain copper-based fish treatments at therapeutic levels, and tests copper levels from 0 to 4 ppm. The kit measures both free and chelated copper, and is for use in fresh and saltwater aquariums, or with ponds.

Copper – a treatment for many parasitic infections – must be monitored in an aquarium or a pond. The copper level can drop too low for the treatment to be effective, or can increase to a point that is detrimental to fish health. Copper is likely even present in your tap water.
